Bruce:

This patch has a gratuitous dprintk. The version below doesn't have it. The version in my git repository doesn't either.

Sorry for the noise...
Tom

Fast Reg MR introduces a new WR type. Add a service to register the region with the adapter and update the completion handling to support completions with a NULL WR context.
